LGT-350 Laser Humidity Analyzer Introduction: The LGT-350 laser humidity analyzer is a high-precision humidity analysis product based on tunable diode laser absorption spectroscopy (TDLAS), which can measure humidity using on-site single ended method. This product uses an imported semiconductor laser as the light source. It adjusts the laser frequency by modulating the working current intensity of the semiconductor laser, so that the scanning range is slightly larger than the absorption line of the measured gas. When the measured gas is absorbed in frequency selection, the laser intensity will decay. This instrument can obtain the concentration of the measured gas by detecting the attenuation information of laser intensity. It can be applied to CEMS and various industries for measuring flue gas humidity, including wood, building materials, papermaking, chemicals, pharmaceuticals, fibers, textiles, vegetables, and food processing. In addition, it can be used for humidity measurement in high-temperature environments such as ceramic drying kilns and electrode drying stoves. Features: 1. Optical non-contact measurement, small drift, and long service life 2. Using the single ended method for measurement, without the need for complex adjustments to the optical path 3. Using a "single line spectrum" measurement without cross interference from background gases 4. Implement alternative calibration technology to solve the production problem of H2O standard gas; High precision 5. Adopting on-site measurement without the need for a preprocessing system; Prevent absorption, blockage, and component damage during pre-treatment and sampling processes; Reduce operational costs Technical parameters: Range: 0-40% (customizable) Linear error: ≤ 1% F. S Span drift: ≤ 1% F. S. /Half a year Zero drift: ≤ 1% F.
